Answer:

1) group

2) period

3) numbers of valence electrons

4) increases

Explanation:

When we move in a periodic table from top to bottom or vice versa along a vertical column , it is said that we are moving along a "group" in a periodic table.

Like wise when we move in a periodic table from left to right or right to left  in a horizontal row , it is said that we are moving along a "period" in a periodic table.

The classification of elements belonging to any specific group of periodic table is dependent on the total number of valence electron. All elements of with in a group have same number of valence electrons however, the orbitals may change.

The atomic number increases while moving from left to right as the number of orbitals in which the valence electron is found also increase in the same direction.

ser-zykov [4K]

Answer:

The correct answer will be option-a synergist

Explanation:

In the musculoskeletal system, the muscles to produce a movement work in group or pairs like hamstrings and quadriceps or biceps or triceps.  The muscles which work is known as an agonist or prime mover.

The muscle which helps prime mover by moving in the same direction and at the same time is known as synergists. The synergists produce a similar motion as the prime mover and also stabilizes the joints which hold the position for smooth movement of agonist.

Thus, synergist is the correct answer.

zhenek [66]
I believe in the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and therefore, slow the rates of glycolysis and the citric acid cycle. Phosphofructokinase is and enzyme that phosphorylates fructose 6 phosphate in glycolysis. It is an important control enzyme in the regulation of cellular respiration. It is inhibited by ATP and is an allosteric enzyme.
